The article discusses the main methods of carbon black granulation, and compares the results with an existing industrial installation. The granulation process is necessary to convert powdered carbon black into homogeneous granules in order to simplify its further transportation and use. Despite the wide variety of granulation methods, there are problems with the uniformity of granules, equipment wear, and the formation of stagnant zones. As a result of the experiments conducted on the laboratory granulator described in the article, photos of the results are provided. Each of the methods used has a description of stagnation zones, which allows us to conclude that the most efficient method is to convert powdered carbon black into granules.
